7 Claims. (Cl. 22S- 97) This invention relates in general to new anduseful improvements in metal severing devices, and more specifically foran improved metal severing maching for severing into sections relativelylarge metal bodies, such as automobile bodies.

Although an automobile body is of a reltaively great bulk, the actualvolume of metal to be found therein is relatively small and may becrushed into a relatively small package. However, in order to crush anentire automobile body at one time there would be required a very largepress. Since such presses are very expensive and because they take upquite a large amount of room, it is not feasible for even the larger ofthe junk yards to own such a press. Accordingly, it is now necessary forthe automobile bodies to be cut up into sizes which the smaller pressesmay handle by using expensive Vcutting means such as an acetylenecutting torch. An acetylene cutting torch is -relatively slow in thecutting up of an automobile body and requires the services of arelatively skilled operator.

It is therefore the primary object of this invention to provide animproved metal severing machine which is s constructed wherebyautomobile bodies or other large bodies may be positioned therein andmay be severed into a plurality of pieces, preferably three pieces withthe individual pieces or sections of the automobile body being of a sizeto be readily handled by existinU presses.

Another object of this invention is to provide an improved metalsevering machine o-f the type for severing automobile bodies or thelike, the metal severing machine including a plurality of verticallydisposed cutters, the cutters being formed of vertically spaced bladeswith the blades of opposed cutters being staggered so that theautomobile body or other body is cut with a severing action.

Still another object of this invention is to provide an improved cutterfor cutting automobile bodies and the like into three sections, thecutter including a first set of fixed cutters and a second set ofmovable cutters, the individual cutters being transversely spaced andcooperating so as to simultaneously form two cuts on an automobile bodywhereby the automobile body is divided into a forward section, anintermediate section and a rear section, the intermediate section beingdisposed within the contines of the metal severing machine at the end ofthe cutting operation, but pushed from one end thereof independently ofthe lfront and rear ends of the automobile body.

A further object of this invention is to provide and improved metalsevering machine for cutting automobile bodies and the like intosections in a simple and quick operation, the machine being of aself-contained type which operates through the use of a hydraulicsystem, the machine being of such a nature whereby once the vehicle bodyhas been positioned within the contines of the metal severing machine,-the machine may be operated by a single operator.

It is an additional primary object of this invention to provide a metalsevering device which is of a size to receive a vehicle body and whichis so constructed whereby the vehicle body to be cut into sections isvertically fed therein utilizing a crane or other hoisting apparatus andwhich has a section thereof severed therefrom by being held in the metalsevering device with that par-t not Lif) Big' Patented Aug. lli, i952ice severed by the metal severing device being suspended by the craneduring the severing operation.

Another object of this invention is to provide an improved metalsevering device for large objects, the metal severing device being soconstructed whereby it includes a bed into ywhich an article to besevered has the lower end thereof lowered, the lower end of the articleto be severed being pushed through the metal severing device and out oneend thereof during the severing operation.

A further object of this invention includes the provision of a metalsevering device of the vertical feeding type, the severing deviceincluding a bed having a bottom wall and upstanding side walls, one endof the bed being open and having extending thereacross a bridge membercarrying irst severing means, a pusher plate being mounted within thebed for movement towards the one end, second severing means beingcarried by the upper edge of the pusher plate for cooperation -with thefirst severing means whereby as a lower part of an article is beingpushed through the bed, it is severed by the first and second severingmeans as the severed portion is pushed out through one end of the bed.

A particular object of the invention is to provide an improved metalsevering device wherein spaced, pointed teeth are employed to tear orrend relatively thin metal sections as compared to a shearing action.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

lReferring now to the :drawings in detail, it will be seen that there isillustrated the metal severing machine which is the vsubject of thisinvention, the machine being referred to in general by the referencenumeral 10. The metal severing machine 1t) includes a supporting framewhich is referred to in general by the reference numeral 12.

As is best illustrated in FIGS. 3 `and 4, the supporting frame 12includes an elongated base plate 14 which is supported upon -a suitablebase or the ground by means of a pair of transversely spaced,longitudinally extending frame members 16. The frame members 16 areconnected together lat spaced -intervals by transverse frame members 18.The base plate .14 extends outwardly of the frame members 16 'and theouter edge portions thereof are braced by suitable gussets 20.

Extending vertically at the two corners of one end of the supportingframe 12 are fixed cutters or metal tearing jaws which are referred toin general by the reference numeral 22. inasmuch as the xed cutters 22are identical with the exception of being left and right, only one ofthe cutters 22 will be described in detail hereinafter.

Each of the txed cutters 22 includes a vertically extending, transverseplate 24 which extends inwardly from the edge of the base plate "14 `adesired distance. The inner edge of the plate 24 is braced by avertically extending, longitudinally disposed plate 26. The plates 24and 26 are reinforced relative to each other by vertically spacedgussets 28.

It is to be understood that the plates 24 and 26 are Idisposed atsubstantially right rangles to each other and include a projectingcorner 30. Extending inwardly and longitudinally from the projectingcorner 30 'are a plurality of spike-like blades `or teeth 32, 34, 36 and38. The blades or projections 32, 34, 36 and 38 each are of a generallytriangular, pointed coniigur-ation, and the tearing or rending point-sof the teeth 32, 34, 36 and 38 are `arranged in an arcuate pattern, asis best illustrated in FIG. 3. rIhus, the individual pointed tearingpoints of the teeth 32, 34, 36 and 38 progressively engage a body beingcut so that a minimum of force is necessary for the cutting action.

Carried by the supporting frame 12 is a guide assembly which is referredto in general by the reference numeral `40. The guide assembly 40includes a transverse plate 42 which is disposed intermediate the endsof the supporting frame 12. The plate 42 is vertically disposed and hasconnected to the upper edge thereof a horizontally disposed top plate`44 which is disposed in yspaced parallel relation to the base plate 14.The top plate 44 overlies `and is secured to the upper ends `of theplates 24 and 26. The plate 44 is reinforced at the end thereof remotefrom the plate 42 by transverse frame members 46 and 48. Disposedcoplanar with the plate 42 land overlying the plate 44 is anotherbracing frame member 50. The plate 44 is further braced by alongitudinally extending frame member 52, as is best illustrated in FIG.5.

Slidably mounted Within the enclosure formed between the base plate 14and the top plate 44 is an upstandng cutter head, ram member or pushermeans which is referred to in general by the reference numeral 54. Thecutter head 54 is formed of a pair of longitudinally spaced,transversely extending plates 56 and 58 which are connected together byvertically disposed, longitudinally extending plates 68, the plates 60being disposed between the plates 56 and 58 and terminally securedthereto. 'lt is to be noted that the cutter head 54 is of a size to passbetween the plates 26 of the xed cutters 22. Disposed opposite verticalcorners of the cutter head 54 opposing .the cutters or iixed jaws 22 arecutters or movable jaws 62. The cutters 62 are identical, with theexception of being left and right, and therefore only one of thecutter-s 62 will be described in detail.

The cutter 62 includes a plurality of vertically spaced spike-likeblades or teeth 64, 66 and 68. The blades or projections 64, 66 and 68are horizontally disposed and include projecting rending or tearingpoints. Also,

'the teeth 64, 66 and 68 `are similar in size and configuration to thefixed teeth 32, 34, 36 and 38 and -are so mounted whereby the pointedends thereof are disposed in an arcuate pattern, as is best illustratedin FIG. 1.

At this time it is pointed out that the teeth 64, 66 and 68 of themovable cutter 62 vare vertically olfset with respect to the teeth 32,34, 36 and 38 of the fixed cutters 22. Further, `as is best illustratedin FIG. 2, the cutting or tearing points of the teeth 64, 66 land 68 arehorizontally oiset with respect to the tearing points of the teeth 32,34, 36 yand'38. Thus the teeth 64, 66 and 68 will pass over and betweenthe teeth 32, 34, 36 and 38 and provide for the tearing or rending of amet-al body, such as automobile body linto three parts. It is pointedout yat this time that the cutters 22 and 62 actually do not shear themetal being cut in the true sense of the word, but actually pierce andtear the metal due to the formation of the various teeth of the cutters.Further, the teeth of the cutters 22 and 62 are so arranged whereby thesection of the body severed b-y the cutters 22 and 24 may be pushedbetween the cutters 22 by the cutter head 54. During the retracting ofthe cutter head 54, the shape of the teeth of the cutters 22 and 62 willresult in the self-cleaning of the cutter 62 whereby the cutintermediate section of a body will be left at the one end of thesupporting frame 12.

In order to guide the cutter head 54, there is secured to the uppersurface of the base plate 14 a pair of longitudinal guide plates 78.Similar guide plates 72 yare secured to the underside of the top plate44 in overlying relation to the guide plate 70. The guide plates 76 and72 yare so spaced apart whereby the cutter head 54 is snugly receivedtherebetween and prevent transverse movement of the cutter head 5-4.

In order to effect movement of the cutter head 54 to provide the cuttingor tearing action, there is provided a pair of horizontally disposed,elongated hydraulic or ud motors 74 and 76. The duid motors 74 and 76each includes a cylinder 78 having mounted therein a piston (not shown)to which there is connected la piston rod 80. The free end of eachpiston rod 80 is secured by means of a fitting 82 to the plate 56 of thecutter head 54.

The `hydraulic motors 74 'and 76 are mounted in overlying relation withrespect to each other and to the supporting frame 12. In order that thehydraulic motors 74 and 76 may be suitably mounted, the cylinders 78thereof are supported between longitudinally spaced pairs of standards84 and 86. The standards 84 are connected together by transverse plates88 which underlie and support those portions of the cylinders 78 remotefrom the cutter head 54. Secured to the standards 86 is lche plate 42,the plate 42 also serving to support the cylinders 78,

- the cylinders 78 passing through the plate 42.

Also extending upwardly from the base plate 14 `are outwardly disposedstandards 98. The standards 90 cooperate with the standards 86 and 84 tosupport platforms 92. and 94 on opposite sides of the hydraulic motors74 `and 76. Carried by the platform 92 is `a power unit 96 which ispreferably in the form of an internal combustion engine. The power unit96 includes a drive shaft 98 on which there is mounted a drive pulley orsprocket 100.

Mounted on the platform 94 is a hydraulic pump unit 102 which maycontain a fluid reservoir (not shown). The pump unit 102 includes adriven shaft 104 having a driven pulley or sprocket 186. Entrained overthe pulleys 108 and 186 and dn'vingly connecting the two together is adrive belt 16S.

Extending from the hydraulic pump unit 182 are hytdraulic lines 118 and112 which are connected to opposite ends of the cylinders 7 8. Thehydraulic lines 110 and 112 are connected to a valve assembly 114 whichis mounted on the hydraulic pump unit 162 so that the flow of uid intoand out of the hydraulic motors 74 and 76 may be lcontrolled to extendor retract the piston rods 88 as is deemed necessary.

In the operation of the present invention, lan automobile body or otherlarge body to be cut into sections is placed on the base plate 14between the cutters 22 and 62, the automobile body being disposedtransversely of the supporting frame 12. The hydraulic motors 74 and 76are then actuated to move the movable cutters 62 towards the xed cutters20. mobile body -is coniined against movement, either vertically orlongitudinally by the cutters 22 and 62 and the plates 14 and 44, theteeth of the cutters 22 and 62 will rend and tear the automobile bodyinto a forward section 116, an intermediate section 118 and `a rearsection 12). The forward and rear sections 116 and 120 drop generally inthe position where they are cut and intermediate section 114 is pushedlout between the cutters 22 to ya position at the end of the machine 19remote from the hydraulic motors 74 and 76.

In order -to prevent jamming of the cutter head 54 with respect to theplates 14 and 44 'and to facilitate the release of the intermediatesection 118, there is secured to the bottom part of the plate 58 atopposite edges thereof vertically disposed, generally triangular plates122. The plates 122 overlie a bottom plate 124 which in turn rests uponand slides on the base plate 14. The Vertical plates 122 serve to liftup the intermediate section 118 from' the base plate 14 and preventsparts thereof from passing under the cutter head 54. Further, once thecutter head 54 has .passed between the cutters 22, the plates 122 willhave a tendency to dump off the intermediate section 118.

From the foregoing description of the invention, it will be readilyapparent that once an automobile body or other large body has beenplaced in the machine 1G, one operator by manipulating a simple controlmay perform the entire cutting action.

A modified form of the invention is illustrated in FIGS. 7-ll, therebeing shown an alternate metal severing device 126. The metal severingdevice includes a bed referred to in general by the reference numeral128. As is best shown in FIGS. lli and ll, the bed 128 includes a pairof lower longitudinal frame rails 130 disposed at opposite sidesthereof. Each of the frame rails 13) includes a base flange 132, anopstanding web '134 and an upper flange A1136.

The bed or enclosure 128 includes side plates 138 which extend upwardlyfrom the frame members or frame rails 139, the side plates 138 havinginner surfaces disposed coplanar with the webs 134. The side plates 138are reinforced along their lower edges by means of flanges '140 whichrest upon the flanges 136 and are secured thereto. The upper edges ofthe side plates 138 are reinforced by top flanges 142 which extend bothinwardly and outwardly of the side plates 138. Each of the side plates138, as is best shown in FIG. 7, is reinforced by a suitable exteriorbracing 144. The ends of each of the side plates 138 are reinforced byvertical flanges 146 and 148. Extending between the frame rails 130 is abottom wall '156. The bottom wall 150 terminates at opposite side edgesthereof in vertical llanges 152 which are secured to the frame rails130. The bottom Wall 150 is also reinforced at longitudinally spacedinter- Inasmuch as the `auto- 6 vals by transverse ribs 154 best `shownin FIG. 8. Also shown in FIG. 8 is the fact that the frame rails 130,extend longitudinally beyond the ends of the side plates 138 and thebottom wall 150.

Extending transversely across the bed 128 at the right end thereof, asviewed in FIG. 8, is a bridge member which is referred to in general bythe reference numeral 156. The bridge member 156 includes a bottom plate158 which has opposite ends thereof resting upon the anges 142 andsuitably secured thereto. Secured to one edge of the horizontal plate158 is a vertical plate 16u. The plate 16@ is reinforced relative to theplate 158 by means of outer gussets 162 and a central gusset 164. Theouter gussets are in the form of upper ends of reinforcing plates 166which extend down along opposite sides of the bed v128 and are securedto the frame rails 138.

Carried by the vertical plate and extending downwardly and away from theopen end of the bed 128 are first metal severing means 168. The metalsevering means 168 are in the form of a plurality of individualtriangular severing plates or spike-like teeth 170 which are bestillustrated in FIG. 8. The teeth 170 are spaced transversely `of theplate 160, as is best illustrated in FIG. 9. Also carried by the plate160, but above the teeth 179, are anchoring teeth 172 for `stabilizingan upper part of an article which is being severed in the metal severingdevice 126.

Mounted within the bed 128 for movement therealong towards and away fromthe bridge member 156 is a pusher plate 174. The pusher plate, means orram member 174 is vertically disposed and is provided at the bottomthereof with a rearwardly extending base plate 176 which rests upon andslides upon the bottom wall 159. The upper edge of the pusher plate 174is reinforced by a rearwardly extending upper plate 178.

ln order that the pusher plate '174 may be guided in its movement towars and a ay from the bridge mem ber 156, there is provided an inwardlydirected ilange 18) adjacent the upper edge of each of the side plates138. The -ilanges 1811 cooperate with inner parts of the flanges 142 andform opposed trackways 182, as is best shown in FIG. 8.

Seated in each of the trackways 182 for longitudinal movement therein isa guide shoe 184. Each guide shoe 184 is secured to an upper part of thepusher plate 174 and is braced relative thereto by means of a diagonalbrace 186, best shown in FIG. 9.

Also best shown in FiG. 9 are the details of the tapered forward edge188 of each of the guide shoes 184. By so tapering the forward edge ofeach guide shoe 184, metal is prevented from jamming the guide shoes andthe tapered forward edge 188 of each guide shoe urges the metal out ofthe trackway in which it is mounted for sliding movement.

Carried by the top plate 178 of the pusher plate are second metalsevering means 199. The second metal severing means are in the form of aplurality of pointed pins or spike-like teeth `192. Each of the teeth'-192 extends upwardly and away from the plate 178, as is best shown inFIG. 8. Further, the teeth are transversely spaced and are staggeredwith respect to the teeth 170 (FIG. 8). r'hus the teeth 178 and 192cooperate to sever or tea-r away a lower portion of an article suspendedwithin the bed 128.

In the operation of the present invention, an article, such as a vehiclebody, to be cut into sections, is lowered into the bed or enclosure 128with the pusher plate 174 in the position illustrated in FIG. 8. Thearticle is lowered by means of a crane or the like. The pusher plate isthen moved to the right with the result that the lower section of thearticle is severed or torn in two by the action of the teeth 170 and'192. The upper part of the article remains suspended by means of thecrane or other hoist means and may then be lowered into the bed forfurther severing after the pusher plate has been withdrawn to its normalposition shown in FIG. 8.

It is to be noted that the framerails 13G extend to the left beyond theside walls 138. Carried by this portion of each of the frame rails is aframework 194. Supported by the framework is a fluid motor 196 of theextensible type. The fluid motor includes a cylinder 198 and a pistonrod G. The piston rod has one end thereof connected to the pusher plateas at 202, shown in FIG. 8. The iluid motor also includes a piston (notshown) connected to the piston rod.

Mounted on the framework 194 is a platform 294. Mounted on the platform294 is a power unit 206 which drives a fluid pump 2438. Also mounted onthe platform 264 is a uid reservoir 219. Suitable iiuid lines 212 and214 are connected to opposite ends of the cylinder 19S. Other iiuidlines 216 and 2&8 extend between the reservoir and the pump, and thereservoir and the four-Way valve 220 mounted on the pump. The Valve 221Bis provided with a suitable control wheel 222. By operating the valve220, the uid motor is controlled to control the movement of the pusherplate whereby the severing lor tearing operation may be performed.

The severing operation carried out by the present invention is notreadily described with exactness but combines a cutting or tearing andrending action imparted to the lighter metallic portions, coupled with avery approximate form of snapping or shearing of the heavier metalmembers such -as the longitudinal frame elements of an automobile body.A degree of crushing of the automobile body will occur, but this is onlyan added advantage since the sections of the body are subsequently to becompacted even further. The present structure readily severs and divides:a body into smaller sections which llend themselves to convenientcompaoting into small bales in presses of relatively small capacity.

As the movable jaws of the severing structure close upon the iixed jawsthereof, the points of the fixed and movable teeth pierce and formadjacent openings in the metallic panels which are present, the furtherclosing of the jaws causing a tearing of the metal between suchperforations, -along with the approximate cutting and tearing of heaviermembers along with a rough or large clearyance jaw or shearing action.Thus, the operation of the machine is described as a rending or tearingand severing operation rather than a shearing operation as the latter isgeneral-ly understood.

It is to be noted that the severing action of this invention does notinvolve cutting as by forcing -a sharp blade against a plate or twoblades past one another in wiping relationship. Such structures -arequickly dulled and jammed when `an attempt is made to cut heterogeneousscrap metal therewith. Instead, this invention relates to metal severingdevices having large spaces between the severing elements, spaces toolarge to be called clearances, and involves a substantially simultaneousperforating and tearing or rending `action which eieetively severs scrapmetal of widely varying nature into pieces of a suitable size whileavoiding the diiiiculties of dulling and jamming.

The foregoing description of the invention is explanatory thereof andvarious changes in the size, shape and materials, as well as in thedetails `of the illustrated construction may be made, within the scopeof the appended claims, without departing from the spirit of theinvention.
